Abstract

A transcutaneous connection between an exterior and an interior of a human or animal body includes a cylindrical skin penetration piece which provides a passage through the skin and has a longitudinal axis that determines the direction of passage through the skin. Wound-healing action and reliable disinfection are effected using an annular flat electrode arrangement, which has a contact surface at an angle to the longitudinal axis, can be fastened to the skin penetration piece. The electrode arrangement includes a flat electrode and a flat dielectric shielding the electrode relative to the surface of the skin, and is designed as a counter-electrode to generate a dielectric barrier plasma between the dielectric and the surface of the skin.
